Oznake: tanke plasti;titanove zlitine;medicinsko jeklo;medicinski vsadki;thin films;atomic layer deposition;titanium alloys;biomedical steel;medical implants;
Alumina and hafnia films produced by the atomic layer deposition were applied to commercially pure Ti and stainless steel 316L specimens for protection under simulated human body conditions. The ALD films were deposited at 180 °C and 260 °C to determine how the deposition temperature affect the film ...

Oznake: friction stir welding;FSW;high-strength dissimilar aluminium alloy;microstructure;microhardness;XRD residual stresses;
This study investigates the effects of friction stir welding (FSW) parameters on residual stresses, microstructural evolution, hardness distribution, and tensile behaviour of dissimilar Al 7075-T651/Al 2017A-T451 joints. Three welding conditions with different welding ratios were analysed to clarify ...

Oznake: kvazikristali;quasicrystals;
New quasicrystals with rare-earth elements and Li are synthesized with the selfflux method. The starting composition involves 62.8 at.% Zn, 28.6 at.% Mg, 3.6 at. % rare-earth and 5% Li. Alternatively, 66 at.% Zn, 24.8 at.% Mg, 3.9 at.% rare-earth and 5.3% Li can be used. Both syntheses result in qua ...

Mnemonic rutile–rutile interfaces triggering spontaneous dissociation of water
Vesna Ribić, Vanja Jordan, Sandra Drev, Janez Kovač, Goran Dražić, Aleksander Rečnik
Izvirni znanstveni članek
Oznake: mineral-water interfaces;atomistic structure;photocatalysis;
Water interaction with mineral surfaces is a complex living system decisive for any photocatalytic process. Resolving atomistic structure of mineral–water interfaces is thus crucial for understanding these processes. Fibrous rutile TiO2, grown hydrothermally on twinned rutile seeds under acidic cond ...

Oznake: airborne-particle abrasion;Yttria-stabilized zirconia (Y-TZP);zirconia-based ceramics;
Porcelain chipping in zirconia-based dental restorations remains a major clinical complication. This study evaluated the effects of airborne-particle abrasion (APA) and yttria content in zirconia on porcelain–zirconia bond strength. Six groups were tested: low-translucency (3Y-TZP) and high-transluc ...

Oznake: aluminium alloys;casting;heterogeneous nucleation;orientation relationship;icosahedral quasicrystals;
This study confirms that crystalline TiB$_2$ particles can act as a potent site for the heterogeneous nucleation of the metastable icosahedral quasicrystalline phase (IQC) formed in cast Al-Mn-Si-Cu-Mg alloys. The results show that a primary metastable IQC phase nucleates on facets of TiB$_2$ partic ...
